ABSTRACT:
Resin is sprayed onto a mandrel by traversing a nozzle axially of the mandrel, reinforcement is applied on the resin layer and continuous filament is wound on the reinforcement and resin. To control the amount of resin sprayed onto particular locations of the mandrel, auxiliary means move the nozzle relative to the mandrel in addition to the axial-traversing movement, such as by moving the nozzle toward and away from the mandrel or by turning the nozzle. Such turning can be about an upright axis to displace the depositing location of the resin spray axially of the mandrel, or about an axis generally parallel to the path along which resin is ejected from the nozzle in a flat fan-shaped spray to change the plane of the spray from a position generally parallel to the axis of the mandrel into a position at a substantial angle to the axis of the mandrel. A shield is swingable either up and down or sidewise between a position offset from the path along which resin is ejected from the nozzle toward the mandrel to a position interposed between the nozzle and the mandrel for intercepting a spray of liquid from the nozzle toward the mandrel.
